Bodrum, site of ancient Halicarnassus, has a beautiful harbour, a splendid Crusader castle and many traditional Turkish houses, of which the Ertegün house, originally two buildings joined by a gate, is one of the best. In 1973 it was converted to a summer residence with an addition at the rear which leaves the old structure totally independent. The old building is made of stone bearing walls with narrow windows, while the new is constructed of round concrete columns with wood infill walls, doors, and a series of adjustable oak shutters that filter light and air through the living and dining areas. The interior spaces flow freely between the new wing and the old.
